v vi About This Manual

Customer Responsibilities The customer should not install this conversion kit unless they are a qualified self-maintenance customer. Only qualified maintenance personnel should perform the installation procedure. Call the Digital Customer Services office to schedule a system conversion. It is the customer’s responsibility to perform a software backup before the Digital Customer Services representative arrives at the site. When a conversion is complete, return the old system module to Digital for credit. Appendix A contains forms that need to be completed by the Customer Services representative and signed by the representative as well as by the customer.

Digital Customer Services Responsibilities To save time, the Digital Customer Services representative should contact the customer and make arrangements to have the customer’s software backed up before arrival on site. Software installation, conversion and testing are not described in the hardware conversion procedure, but such tasks are part of the overall system conversion. The customer should contact a Digital sales representative to transfer an existing software product services contract to the MicroVAX/VAXserver Systems group. After the representative installs the conversion kit, they are to complete the following forms and then remove them from this document by tearing them along the perforated line. The following forms are in Appendix A. • Customer Services Worksheet • Installation Receipt–Customer Copy • Installation Receipt–Customer Services Copy • Return Material Worksheet The Digital Customer Services representative should give the customer the signed Installation Receipt - Customer Copy. They should include the signed Customer Services Copy with the system module that is being returned to Digital to ensure that the customer receives credit. A self-adhesive mailing label is contained within this kit. Peel off the label and attach it to the package containing the system module to be returned. About This Manual vii
